Thanks for the replies guys. I failed to say that I have researched 'the lurch" issue extensively I just didn't know that's what it was called.

Weasel- Thank you for the technical reply and it at least eases my mind that someone else has experienced this. I was a dealer tech for about 5 years but now I work at an independant, basically a sub-contracter for the shop itself as i'm the only factory trained BMW tech locally here.

I do have GT1 with Progman which is about 2 years old. I reprogrammed with this but I'm sure it's not the latest version. I may give the Dinan a try if I can find it to be worth the 3-400 bucks...

Since your intimate with your ride I have a couple more questions.

-What tires are you running?

-Do you have any squeaks or rattles? Especially from the rear gate?

Thanks in advance!
